Substitute Part Grouping Explanation

Substitution of the VB30150C-M3/4W is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part STPS30150CG-TR, manufactured by STMicroelectronics, meets all mandatory equivalence criteria. Variations in forward voltage (Vf), reverse leakage current (Ir), and maximum junction temperature do not disqualify substitution when the core electrical ratings and package specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the VB30150C-M3/4W and STPS30150CG-TR are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent substitution in applications requiring 150 V, 15 A Schottky diode arrays in D2PAK surface mount packages.

The STPS30150CG-TR demonstrates superior performance characteristics in forward voltage drop (920 mV versus 1.36 V at 15 A) and reverse leakage current (6.5 µA versus 200 µA at 150 V), resulting in lower power dissipation and improved leakage performance. The STMicroelectronics part also supports a higher maximum junction temperature of 175°C compared to 150°C for the Vishay component.

Selection between these parts should be based on availability, supply chain requirements, and application-specific thermal or efficiency considerations. Both parts are electrically and mechanically interchangeable within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can STPS30150CG-TR be used as a direct replacement for VB30150C-M3/4W?

A: Yes. Both components share identical core electrical specifications (150 V reverse voltage, 15 A average rectified current, Schottky technology, 1 pair common cathode configuration) and are packaged in the same TO-263-3 D2PAK surface mount format. Pinout and mechanical dimensions are equivalent.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Vishay versus STMicroelectronics), forward voltage characteristics (1.36 V versus 920 mV at 15 A), reverse leakage current (200 µA versus 6.5 µA at 150 V), maximum junction temperature (150°C versus 175°C), and packaging format (Tube versus Tape & Reel). These differences do not affect functional substitution.

Q: Does the lower forward voltage of the STPS30150CG-TR affect circuit compatibility?

A: The STPS30150CG-TR exhibits lower forward voltage drop, which results in reduced power dissipation and improved efficiency. This is a performance advantage and does not create compatibility issues. Circuits designed for the VB30150C-M3/4W will operate with the STPS30150CG-TR without modification.

Q: Are both parts RoHS compliant?

A: Yes. Both the VB30150C-M3/4W and STPS30150CG-TR are ROHS3 compliant and carry unlimited moisture sensitivity ratings (MSL 1).

Q: What is the significance of the D2PAK package designation?

A: D2PAK is a surface mount package format with 2 leads plus a tab for thermal management. Both parts use the identical TO-263-3 D2PAK configuration, ensuring mechanical and thermal compatibility on PCB layouts designed for either component.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The STPS30150CG-TR supports operation up to 175°C junction temperature, while the VB30150C-M3/4W is rated to 150°C. For applications approaching or exceeding 150°C, the STMicroelectronics part provides additional thermal margin.
